I recently had a drainage system installed around the perimeter of my basement. The guy that did the work said I should attach furring strips to the foundation walls and attach a vapor barrier to that. He also said to run the bottom of the vapor barrier into the gap he left where the floor meets the foundation wall in case there is any seepage.
I have read some information on this blog that says I shouldn't do that. One says I should install foam insulation directly onto the foundation wall and put furring strips over that and then sheetrock.
My main question is... if I attach the foam directly to the foundation and happen to get water, is there enough room for the water to run down the wall and into the french drain??
Also, if this is possible, after I install the foam insulation can I build a 2x4 wall in front of that and if so do I need to install a vapor barrier at that point?
Thanks for any help and advice.
